I'll try that, and I'll grab a screenshot of the mios studio screen as well.
Thanks

Hi all,
Trying to finnish my so long in the making mb 6582. Hardware has been done for some time, Got stuck trying to put the bootloader on the PIC18F4685's. Quit for a while, now I have some free time again and am trying to finish. I am trying to use a BK precision 844USB burner that I have at work. It supports the pic in question. I have a known good core module I am testing with. Either I have something wrong in the configuration or the wrong file or who knows what anymore..... Attached is a PDF of the screenshot of my programmers config screen, Can someone look and see if I have the right settings? This is not my first midibox, but in the past I have used pics with the bootloader on them already. I am not wanting to build a new burner b/c I already have acces to this one and funds/time are tight. Again, i know this core works, I have used several 18F452's on it.
New info, Last night I tried again and can now see a sysex rewquest coming from the core, but when I try to upload MIOS in MIOS studio, it says error unexpected sysex request, and shows the expected request and it seems the unexpected one just has an extra pair of 00 at the begining?
What have I done?
Thanks in advance.....

Nice work! That LCD looks ok, I've mounted one that looked worse than that....
Where are you getting The stm32 boards? Last I looked Smash didn't have them? Sorry If I missed an anouncement, my work has kept me away from midibox the past couple months and likely the next few but I try to check up on the topics that I have been following. I ordered some IIC modules to get started on this but they have set in a box since Christmas :( I'll check the WIKI page and see what's up.
Keep up the good work!

I remember someone posting these a long time ago. What I don't remember is any midibox, or anything else for that matter, that actually used them. They doo look cool as all get out, but I think they are not so cheap. Motorfaders are likely cheaper.

How did you guess :)
Because I am......Quite happily.....as long as I don't spend "too much time" back in the lab "ignoring her" ;)
I did an apprenticeship in electronic engineering (in the late 80's) and almost all of the first year of that was spent in the machine shop. If I had access to a milling machine and a decent pillar drill i'm sure I could make quite a nice job of the panel but I may have to make do with a hand-held router and a dremel :(
Mori Seiki who manufacturer cnc machine tools are a customer of mine so I might see if I can call in a favour??
Phil
Right, I was assuming you didn't have acces to a proper machine shop since you were asking about how to cut the slots. Machine shop access should be a right, not a privilege. :D

Awesome work! I ordered some IIC MIDI boards and PIC's from Smash TV in hopes of playing around with this over my Christmas Holiday. I have two weeks off and one with no Wife (she has to work). Some extra free time in january too. Phil, you must not be married to be making so much progress so quick!
I think you will find Front panel construction to be the biggest challenge yet! Especially since you seem to breeze right through coding.

Recieved mine on friday. Thanks!

If you're really worried about security you can rent my jack-Russell for a small fee... better than any burglar alarm or shotgun.
Just out of interest, you guys who collect all this vintage gear, is it for playing with or keeping safely wrapped up somewhere out of the way. I have a friend who has literally 1000s of transformers which nobody is allowed to touch, not even him.
+1 for the jack russel. such wonderful dogs. Major little dog syndrome though (Theyr'e bred for that I think ;) ) My wife has one but we have no fence at our new home and her parents are kind of attached anyway, so it lives there and we have visitation rights....
I play my 6 vintage synths/drum machines......well, Iplay them as much as my non vintage ones anyway, which lately has not been nearly enough.......

(I wish I could just stick to doing one thing !!!)
I know the feeling. 8)
I am going to try and get some cheap LED fixtures for chistmas so I can experiment with this project. Let me know when you update the code.
Thanks,

Ahh yes, that's correct on RDM. I have been reading, slowly over the last 10 months, a very good book on show control, thought the title and name escape me at the moment. I went back to it last week and decided it has almost enough info to not need to purchase the official DMX spec... and tons of other stuff. I'll edit this post with the title and name when I A) remember it B) long enough to post it....
as for being bitten by the bug, that's why I am trying to finish my other projects first......even though this one would probably be used more often, it seems I am in the church (where I plan to use this device) much more than my own studio anymore.
Anyway thanks for sharing your work, I'll try to look it over soon, though I haven't looked at your code I downloaded last week yet..... I have been commisioned by a local church to install a sound system and owe them a proposal next week. Paying gigs always take precedence ;)
-
TK, I think the comments in the ASM files are already fairly descriptive. Any further info should be obtained from a true documentation source like the wiki or ucapps.de in my own opinion. Otherwise there will be a small novel in every asm file...
I agree, but I have had a programming class and a microproccessor class and even thought it was motorala HC11, I may be blinded by my understanding...
-
Wow, that's good quick work youv'e done.
I second that your casing can easily be the most expensive part of a design.
Do you have any plans to implement the second data pair of the DMX spec? I think RDM uses this, but I don't currently own or work with any gear that needs this, just wondering. I assume so far that you are just using the standard IIC midi module with 5 pin XLRs instead of 5 pin DIN's?
Your really tempting me to start playing around with this, but I must resist..... Must finish other projects.......must resist.......Aaaaarghhhh.....must resist....

And all the libraries on the cadsoft site are here:
Enjoy.

there are post's in the forum for motorized pots, do a search. I don't recomend them though, too slow.
Welcome and enjoy.
-
Nice look, I think I'll keep it....

There are some switches like that in the eagle Switch-misc library. I have the same or similar switches taken from old 911 call center equipment that I am using for my seq. I started on the vero board but I am currently working on a pcb. I got halfway through a 4x8 matrix board before I decided it probably would be easier in the long run and more reliable to make a pcb. I would have needed two of these for the entire Button duo led matrix.......I don't remember if that library is a stock library or one I dl'ed from cadsoft, and I think there were some other switch libraries with similar. Mine were Schadow switches and the lib I used was not a schadow lib, but there are many clones of this type of switch.

Bit banging probably would work. By using IIC though, you could have the possibilities to mix and match MIDI, DMX, and RS232 (as it seems phil has gotten this working) in an app.that leaves the cores built in midi interface for mios studio uploads and what not. and no hardware chnges so we can use the extra core we all already have lying around ;)
Phil
I have DL'ed the code for the magnulator and will try to find some time to look over it, though to date I have not been the most succesful coder to date, I do enjoy it, just wish I had more time for it.

Unfortunately, I havent found a free copy of the official DMX-512 Spec. but it only cost's about 30 USD to buy it..... I would prefer to stick to the spec.
-
I don't think anyone has mentioned it so: The possibility for more IIC MIDI (or other) modules. 8 or 16 would be awesome. I'd also love to have a 16x16 BLM, for drum editing of course.
Someone mentioned labels and a usb keyboard, no need for usb keyboard, we just need a shift function to use the BLM as a text input device...could also be used for direct acces to patterns (or is this alredy possible, I havent hooked up my BLM yet).

I'm really in no hurry so you don't need to worry about mine, even though I was one of the first to order. Glad to hear they have come in. As long as I get mine by mid december I am happy.
Thanks for organizing this order,
AB

Awesome, your'e not in a hurry. Let's see if anyone else is interested. get a little feature list going, and see when the new core comes out. I also think that the IIC DMX module is the way to go so maybe that should be the starting point. could the 16f88 be replaced by another chip with more RAM?
Of course it would be rediculously cool to have motorized faders...... all the standard midibox control options should be possible, pots or encoders, buttons, etc. the modularity and customization of midibox is it's beauty.
I need the ability to cue lighting scenes, recall audio settings from our digital mixer, trigger sound effects and backing tracks, trigger video clips and remote control a video switcher. I could think of more things too, but this is the core list.
AS for light boards, I haven't used many but the nsi mc24/48 that I had to learn from nothing in 3 months while programming a show, is an akwward and downright buggy piece of junk. it even blew a fuse on the video card which the prevents the console from booting with no indication of what the problem is. and the 24/7 tech support promised in the manual is an answering machine .... they did call back the next day, and the guy knew what the problem was, but still come on, that is NOT 24/7 support, thank god it wasn't an hour before the show when it blew. an easy fix once I knew what the problem was.
end rant.
Anyone else?

Interested , yes. I have been planning to build a MIDIBOX Show control to use at my church, hence my interest in your rs 232 work. I think it is possible, but you may wish to wait for the new core that TK is working on. I believe it will be far more capable. However I really need to finish the projects I am currently working on (or they will keep getting pushed off for new projects). I would be glad offer some discussion on the project. If your not inj a big hurry, I would be willing to collaborate with you. I am hoping to be done all of my currently in progress midibox projects by the new year. perhaps the new core will be ready by then.
My concept was based on using midi for lighting, as we have a lighting board that will accept some midi comands. But, if an IIC DMX module could be developed, that wopuld be more useful. I hate that console anyway, but it is what we have. I need at least 256 DMX channels. I wanted to be able to control all the equipment in our control booth from one console, so I need DMX, RS 232, and Midi. Of course contact closures could be useful and easily implemented.
Gotta run, hopefully this will spark some discussion.

imagine that you only have to press a "gather all settings from synths" button and all connected hardware is sending their patches to the sequencer for saving as a whole project.
if you implement a flash card for saving all data, please let us use the biggest cards available (16 gigabyte ?)
Heh, that would be a lot of sysex data streaming in all at once. nice idea though. would definitely have to do a request synth 1, wait for rx, request synth 2, wait...etc.
AS for 16 GB cards, hah, you could store a rediculous number of patches on a 512Mb card. of course if there is not technical reason to limit the size of the card I'm sure TK wouldn't limit you, just doesn't seem to be his style.
and of course what would you do when the 32 or 64 Gb cards come out.......
-
Nice Case, I love seeing projects using recycled parts!

Are there nightly's for windows? the ones I come across are Linux.....And I'm not using Linux yet. I downloaded a more curent 2008-09-06 r1238 version for windows and will try that. I had the converted eagle libraries for the components that weren't already in kicad, I'll try the new version and if it still fails I'll add the other libraries.
Thanks,

Well, that doesn't work, it only lets you put in four numbers in each box. here are the screenshots of MIOS studio. Any more Ideas?
